A lot of data is misused without the data owner being aware of it. Software developers must ensure the security user data on their system. Due to the size of the market that houses data, the security of record databases must be of great concern. Cryptographic systems or data encryption can be used for data security. The Merkle-Hellman Knapsack algorithm is included in public-key cryptography because it uses different keys for the encryption and decryption processes. This algorithm belongs to the NP-complete algorithm which cannot be solved in polynomial order time. This algorithm has stages of key generation, encryption, and decryption. The results of this study secure database records from theft by storing records in the form of ciphertext/password. Ciphertext generated by algorithmic encryption has a larger size than plaintext.

Penerapan Algoritma Mixed Heuristic dalam Penilaian Ujian Pada Jurusan Pendidikan Teknik Elektro Universitas Negeri Medan Sari, Ressy Dwitias; Rahmadani, Reni

During the COVID-19 pandemic, teaching and learning activities switch of technology such as e-learning. In the Department of Electrical Engineering Education, Universitas Negeri Medan, 80% of electrical lecturers provide multiple choice exams and short answers. The scoring system cannot be performed automatically by a computer. The algorithm used in this study is a Mixed Heuristic algorithm. This algorithm is used because it is an effective way of working for sentences of more than 1 word. And give the results in the form of ranking in the form of similarity proportions. From the process of using a mixed heuristic algorithm, it can be proven that this algorithm can perform keywords on the answer keys and answers of users or students. The algorithm is also able to provide value to a user or student's answers
